Description

The US72 and US73 provide a monolithic solution for driving single-coil fans. The bridge drivers provide bi-directional current through the single phase motor winding.

US72: The tachometer/Frequency Generator (FG) version produces a logic signal, which is aligned with the Hall plate signal.

US73: The Rotation Detector (RD) / Alarm Signal version has a low output in the normal condition. When a locked rotor condition occurs the RD changes to a high state.
